When gasoline is blended, it is given a Reid Vapor Pressure (RVP) number which reflects its ability to vaporize or mix with air at a given temperature range. Gasoline vapor pressure is measured by putting a sample of fuel inside a closed container and applying a specified amount of heat to the container for a certain amount of time. RVP will vary from about 7.0 PSI during the summer to approximately 13.5 PSI during the colder months. Service stations selling a large volume of fuel will normally have the correct blend to work well at all times throughout the year in their local area. When the weather is very cold, gasoline must be able to vaporize very quickly in order for an engine to start and warm up properly. If summer blend fuel is being used in the winter, little or no vaporization will occur. Droplets will form causing flooding and very hard starting. If winter blend fuel is being used during the summer months, it may cause vapor lock (boiling fuel) inside the fuel lines, fuel pump, or carburetor. This will cause warm engine driveability problems and hard starting when warm.
• 1 Gallon = 128 Ounces • 128 / (Desired Ratio) = Ounces of oil for every 1 gallon of fuel. • 128 / 40 (40:1 Ratio) = 3.2 ounces of oil for every 1 gallon of fuel. Always mix ratio in 5 gallon increments. NOTE: A 40:1 premix should always be used during engine break-in or after re-building the engine.

Changing temperature, barometer, altitude, and fuel supply are just a few of the factors that can affect the day to day performance of your engine. That is why using Exhaust Gas Temperatures (EGT) are important for maintaining optimum performance. There are two methods for helping you determine what the EGTs are for your machine. Piston wash and the coloring of your spark plug. The piston wash is by far the most valuable tool in concluding EGTs, with the spark plug color running a distant second. Use the illustrations below to help establish the EGTs for your machine.

Maintenance BREAK-IN PROCEDURES
ENGINE MAINTENANCE
Engine Break-In Procedure
Exhaust Valve Cleaning
The first tank of fuel is considered the break-in period for the engine. During this time it is critical to not operate the engine at full throttle for more than a few seconds. Vary the throttle speed as much as possible. Monitor engine temperatures and fluid levels often during the break-in period.
The exhaust valve guillotines must be cleaned to ensure maximum engine performance and throttle response.
NOTE: During the engine break-in period, verify the oil injection system is functioning by monitoring the oil level in the oil tank. If the oil level does not drop, inspect the oil injection system. Polaris recommends filling the oil tank and pre-mixing the first full tank of fuel with Premium 2-Cycle Semi-Synthetic Oil when the engine is either new or refurbished (new pistons, crankshaft, cylinder, etc.). Polaris semi-synthetic engine oil will seat the rings faster than when using Polaris VES Gold Plus oil. After the break-in period use Polaris VES Gold Plus engine oil for normal operation.
Fuel/Oil Premix Ratio During the break-in period, premix the first tank a fuel (10 US gallons) using a 40:1 (fuel:oil) ratio.
FASTENERS
EV ASSEMBLY GASKET
1. Remove the vent hose from the EV base fitting. 2. On the MAG VES assembly, remove the two fasteners that secure the valve assembly to the cylinder. Remove the cover after the assembly is removed from the engine. 3. On the PTO VES assembly, remove all four screws. Remove the cover and spring from the EV base. 4. Remove the two screws that secure the lower steering shaft clamp to the overstructure. Doing this will provide clearance to remove the EV valve assembly.
Formula = 1 US Gallon = 128oz. / 40 (Desired Ratio) = 3.2oz. for every 1 US gallon of fuel. 10 US gallons of fuel requires 32oz. of oil to achieve a 40:1 premix ratio. Always mix fuel and oil 5 gallons at a time. Never fill the tank with fuel and then add oil.
Drive Belt Break-In Procedure The break-in period for a new drive belt is 30 miles. During this time, vary the throttle position under 50% and limit full throttle use. New drive belts that feature a sanded finish should be first washed with warm, soapy water and allowed to air dry prior to use.
5. Carefully extract the guillotine out of the cylinder. Discard the gasket. Do not excessively push on the lower steering shaft when removing the EV assembly. 6. Using a clean rag or shop towel, remove the oil residue from the cylinder, guillotine, and EV base.
Always take time to warm up the belt and driveline prior to operating the snowmobile. Free track and skis from the ground before engaging throttle.

7. Inspection: • Inspect the guillotine for signs of damage. Replace guillotine if damage is found. Inspect the cylinder and piston for damage if guillotine is damaged. • Inspect the spring. Replace if rusted, damaged, or bent. • Inspect bellows. Replace if damaged or excessively worn. • Submerse the assembly in parts cleaner. Thoroughly flush the EV housing base, bellows, and mating surfaces. Verify no carbon is in the gas transfer ports. • Clean the guillotine with brake cleaner and a piece of fine steel wool. Clean only to remove hardened carbon deposits. 8. Once clean, rinse blade with mild detergent and water. Dry completely. 9. Install a new gasket, then reinstall the EV assembly. Apply Loctite 242 to the fastener threads, then torque to specification.
=T Exhaust Valve Housing Fasteners 12 Ft.Lbs. (16 Nm) - Apply Loctite 242 10. Reconnect the vent hoses. 11. Torque lower steering post clamp fasteners to specification.
Inspect/replace the spark plugs as outlined in the periodic maintenance table. The spark plugs can be serviced by opening the left and right door panels. Replace a spark plug when the following occurs: • Spark plug is damaged/insulator is cracked or missing • Plug electrode/insulator is fouled • Replace at interval in maintenance table When inspecting a spark plug, take note of the electrode and insulator color. A light brown/dark tan color indicates the engine is running properly. If the spark plug electrode/insulator is white, the engine may be running lean. Inspect the engine, throttle body boots, etc. for air leaks. If the spark plug electrode/insulator is black, oily, or shows heavy soot, the engine may be running rich. Inspect the engine, fuel system, and lubrication system for problems. Set the electrode gap to specification before installing a new spark plug.

Maintenance Surge Tank
NOTE: Squeeze the coolant hoses to purge air from the cooling system.
Keep the level of the coolant inside the surge tank at the FULL COLD level mark (A) when the coolant is at room temperature. Always add coolant when the cooling system is COLD.
A
7. Continue to run the engine until the engine temperature is at least 130° F (54° C). Secure the bleed screw after the thermostat begins to open and coolant begins to flow out of the bleed screw. 8. Verify the tunnel coolers and front heat exchanger begin to warm as the engine continues to run. 9. To remove air from the tunnel cooling system, the vehicle should be pivoted upwards in four directions (nose up, left side up, rear bumper up, and right side up) to move any air pockets in the system to the surge tank. 10. The thermostat outlet bleed screw may need to be opened slightly to allow any residual air trapped in the outlet to escape. 11. Verify that all of the coolers are warm, including the tunnel-length cooling system. Shut off the engine once the tunnel coolers are sufficiently warmed-up. Release the parking brake.
CAUTION
CAUTION Never remove the surge tank pressure cap when the cooling system is warm. Severe burns to skin may occur from escaping coolant or steam.
Recommended Coolant Use Polaris Premium 60/40 pre-mixed antifreeze. This premium antifreeze is rated for temperatures down to -62°F (-52°C).
Always verify all tunnel coolers / heat exchanger are warm to the touch. A cooler or return hose that is significantly “colder” than another cooler or hose is an indication of trapped air within the cooling system. 12. Allow time for the coolant temperature to cool. Recheck the coolant level in the surge tank. Add more coolant if required. Reinstall the surge tank cap.
Cooling System Bleeding 1. Allow the cooling system to cool completely. Open the right side engine compartment door panel. 2. Verify the coolant level in the surge tank is at the COLD mark. Fill the surge tank if required. Loosely install the pressure cap. 3. Open the thermostat housing bleed screw. Wrap a clean shop towel around the housing to absorb any coolant that may flow out of the bleed screw. 4. Elevate the front of the machine slightly. 5. Apply the parking brake and start the engine in a well ventilated area. 6. Immediately add coolant to the surge tank if the coolant level drops significantly after the engine started. Watch the level and add more coolant until the level stops dropping.

3. Loosen the bleed screw (A). Verify a stream of oil flows from the bleed screw. 4. After bleeding oil pump, secure bleed screw and wipe up oil residue. NOTE: Any time the engine is disassembled or repaired, it is important to purge air within the oil supply hose and oil pump.
Oil Tank/Clutch Cover Service The oil tank is mounted to the clutch cover assembly. The oil tank/clutch cover assembly can be removed from the vehicle to access components within the engine compartment. NOTE: Because of the relative ease of removing both the oil tank and clutch cover at the same time, both processes have been combined although not all service procedures will require the removal of the clutch cover. 1. Open the engine compartment door panels, and remove the hood.
3. Disengage the rubber strap from the cover at the back of the oil tank. 4. Remove the screw securing the bottom of the tank to the clutch cover. 5. Remove cap. Remove the ECU bracket from the oil tank. Reinstall the fill cap. Disconnect the oil level sensor. 6. Disconnect the two wire harness connectors from the ECU. 7. Disconnect the wire harness connections at the regulator/rectifier, and capacitor. Release the wire conduits from the rosebud connectors. 8. Remove the four nuts securing the clutch cover from the chassis. 9. Carefully pull up and release the cover from the mounting studs. 10. Using a needle nose pliers, slide the clamp back and remove the oil supply hose at the filter location. Use the pliers to pinch the supply hose to prevent oil loss. 11. Installation is the reverse of removal. After installing the supply hose on to the filter and installing the clamp, hold the oil tank high in the engine compartment with the supply hose pointed down to allow the trapped air to bleed upwards into the tank.
CAUTION Verify the oil supply hose is not kinked after installing the oil tank/oil supply hose. 12. Install the ECU bracket, and fill cap. 13. Torque the lower tank screw to specification. Install the rubber strap.

Belt Deflection Inspection
FILLFILTER CAP/ECU BRACKET OIL
Too much belt deflection is when the belt is too long or the center distance is too short. The initial starting ratio will be too high, resulting in performance loss. This is due to the belt rising too high in the drive clutch sheaves upon engagement (A). Not enough belt deflection (B) is when the belt is too short or the center distance is too long. The initial starting ratio will be too low. In addition, the machine may creep when the engine idles, causing damage to the internal face of the drive belt.

Brake Fluid
= In. / mm. WARNING
Throttle Lever Free Play: 0.010-0.030 (.25-.8mm)
Do not over fill the master cylinder. Fluid expansion could cause brakes to lock, resulting in serious injury or death. Once a bottle of brake fluid is opened, use what is necessary and discard the rest. Do not store or use a partial bottle of brake fluid. Brake fluid is hygroscopic, meaning it rapidly absorbs moisture from the air. This causes the boiling temperature of the brake fluid to drop, leading to early brake fade and the possibility of serious injury
The inline adjuster should only be used to set free play and to remove cable slack that occurs if the cable has stretched over time.
Inspect the reservoir to be sure it contains the correct amount of fluid. Use only Polaris DOT 4 high temperature brake fluid. Change fluid every 2 years or whenever the fluid is dark or contamination is suspected.
